在Cisco路由器上建立一个名为zw246的DHCP地址池 地址池的IP地址是176.115
问题详情
在Cisco路由器上建立一个名为zw246的DHCP地址池，地址池的IP地址是176.115.246.0/24，其中不用于动态分配的地址有176.115.246.2～176.115.246.10，缺省网关为176.115.246.1，域名为tj.edu.cn，域名服务器地址为176.115.129.26，地址租用时间设定为6小时30分钟。下列DHCP地址池的配置，正确的是
A.Router (config)#ip dhcp pool zw246 Router (dhcp-config)#ip dhcp excluded-address 176.115.246.2 176.115.246.10 Router (dhcp-config)#network 176.115.246.0 255.255.255.0 Router (dhcp-config)#default-router 176.115.246.1 Router (dhcp-config)#domain-name tj.edu.cn Router (dhcp-config)#dns-server address 176.115.129.26 Router (dhcp-config)#lease 0 6 30
B.Router (config)#ip dhcp excluded-address 176.115.246.2-10 Router (config)#ip dhcp pool zw246 Router (dhcp-config)#network 176.115.246.0 255.255.255.0 Router (dhcp-config)#default-router 176.115.246.1 Router (dhcp-config)#domain-name tj.edu.cn Router (dhcp-config)#dns-server address 176.115.129.26 Router (dhcp-config)#lease 0 6 30
C.Router (config)#ip dhcp excluded-address 176.115.246.2 176.115.246.10 Router (config)#ip dhcp pool zw246 Router (dhcp-config)#network 176.115.246.0 255.255.255.0 Router (dhcp-config)#default-router 176.115.246.1 Router (dhcp-config)#domain-name tj.edu.cn Router (dhcp-config)#dns-server address 176.115.129.26 Router (dhcp-config)#lease 0 6 30
D.Router (config)#ip dhcp excluded-address 176.115.246.2 176.115.246.10 Router (config)#ip dhcp pool zw246 Router (dhcp-config)#network 176.115.246.0 255.255.255.0 Router (dhcp-config)#default-router 176.115.246.1 Router (dhcp-config)#domain-name tj.edu.cn Router (dhcp-config)#dns-server address 176.115.129.26 Router (dhcp-config)#lease 30 6 0请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：C
解析：Cisco路由器DHCP地址池的配置：步骤一：首先排除不用于动态分配的地址(config)#ipdhcpexcluded-address176.115.246.2176.115.246.10步骤二：配置一个名为zw246的DHCP地址池(config)#ipdhcppoolzw246步骤三：配置动态分配的地址段(dhcp-config)#network176.115.246.0255.255.255.0步骤四：配置缺省网关(dhcp-config)#default-router176.115.246.1步骤五：为客户机配置域后缀(dhcp-config)#domain-nametj.edu.cn步骤六：为客户机配置DNS地址(dhcp-config)#dns-serveraddress176.115.129.26步骤七：配置租借期为6小时30分钟(dhcp-config)#lease0630，格式为lease天数小时数分钟数
